This weekly report is almost a week late due to the very high number of
calls to be processed and identified this week; the biggest week of the year
for nocturnal migration this autumn. In total, 4,162 flight calls were
recorded and it was a sparrow extravaganza.  Not only was there a high
number of sparrows but there was a great diversity, with a total of 13
possible sparrow species. The most common sparrows were Savannah,
White-throated, Lincoln's/Swamp, and Song. The most common warblers were
Yellow-rumped, Common Yellowthroat, Palm, and Blackpoll. Due to the number
of rare species this week, I am listing them first and giving each species a
confidence rating based on the strength of the call and the conformity of
the call to typical spectrogram patterns for that species. Thus the
rare/unusual birds were:

 

Orange-crowned Warbler - 1 (probable)

Pine Warbler - 3 (probable)

Prairie Warbler - 2 (probable)

Prothonotary Warbler - 1 (possible)

Field Sparrow - 5 (possible)

Grasshopper Sparrow - 1 (probable)

Fox Sparrow - 2 (possible)

White-crowned Sparrow - 5 (probable)

Indigo Bunting - 1 (probable)

 

The total number of night flight calls for the period from the evening of 28
September to the morning of 5 October 2012 is as follows:

 

Semipalmated Plover - 2

Black-capped Chickadee - 3

Golden-crowned Kinglet - 7

Veery - 1

Swainson's Thrush - 40

Hermit Thrush - 32

American Pipit - 3

Northern Parula - 12

Magnolia Warbler - 35

Cape May Warbler - 1

Black-throated Blue Warbler - 3

Yellow-rumped Warbler - 368

Black-throated Green Warbler - 25

Pine Warbler - 3

Palm Warbler - 132

Bay-breasted Warbler - 5

Blackpoll Warbler - 67

American Redstart - 1

Prairie Warbler - 2

Other unidentified warblers of the genus Setophaga - 6

crisper, see http://www.johnfkearney.com/Nocturnal_Migration.html
